Dynamic light scattering (DLS) from various sample media (solutions, liquid crystal cells, thin surface and free standing films, composite media, etc.) is analysed using an ALV-6010/160 digital correlator that enables measurements in the range of 10-8-103s and a He-Ne laser (25 mW at 632.8 nm) as a light source. The normalized intensity autocorrelation function of the scattered light is detected. Different types of scattering geometries and scattering angles in the range 0-140o can be selected. The temperature of the sample can be varied from room temperature up to 150 oC. By combining incident beams from the He-Ne (632.8 nm) and Argon Ion (514 nm or 488 nm) laser sources the setup can be extended to dual-colour cross-correlation spectroscopy.
